Abstract

A system and method that allows caregivers, central monitoring companies, and other persons to monitor disabled, elderly, or other high-risk individuals and obtain automatic notification of falls by such an individual, including, but not limited to, falls that require assistance. One or more 3D motion and sound sensors can be placed in the monitored individual'"'"'s room and provide continuous data which is analyzed to determine when the individual has fallen.

Claims

1. A computerized method for detecting when a monitored individual has fallen within a fall zone, the method performed by a computerized monitoring system and comprising:

defining a virtual fall zone within an area that an individual to be monitored is located;

receiving video data from one or more 3D motion and sound sensors capturing live video data from the area, wherein video data from the one or more 3D motion and sound sensors comprises data representing 3D coordinates of body joints for the individual and a general skeletal outline of the individual;

using the data from the one or more 3D motion and sound sensors, determining that the individual has become at least partially located within the virtual fall zone;

determining that the individual has remained at least partially located within the virtual fall zone for at least a pre-determined amount of time; and

upon determining that the individual has remained at least partially located within the virtual fall zone for at least the pre-determined amount of time, automatically transmitting an alert to at least one of a computerized communication system and a centralized monitoring system.

2. The computerized method for detecting of claim 1, wherein the virtual fall zone is proximate to a portion of a floor within the area.

3. The computerized method for detecting of claim 1, wherein a live video feed of the monitored area received from the one or more 3D motion and sound sensors is continuously displayed on a centralized monitoring primary display that is remotely located from the monitored area.

4. The computerized method for detecting of claim 3, wherein the live video feed is displayed on a centralized monitoring alert display after the alert has been transmitted to the centralized monitoring system, wherein the centralized monitoring alert display is a separate display from the centralized monitoring primary display.

5. The computerized method for detecting of claim 1, wherein a live video feed of the area received from the one or more 3D motion and sound sensors is continuously displayed on a centralized monitoring alert display after it has been determined that the individual has become at least partially located within the virtual fall zone.

6. The computerized method for detecting of claim 1, wherein a live video feed of the area received from the one or more 3D motion and sound sensors is continuously displayed on a centralized monitoring alert display after the alert has been transmitted to the centralized monitoring system.

7. The computerized method for detecting of claim 1 further comprising updating a database in communication with the computerized monitoring system regarding the determination that the individual remained at least partially located within the virtual fall zone for at least the pre-determined amount of time.

8. The computerized method for detecting of claim 1, wherein a previously designated caregiver is notified by electronic message regarding the determination that the individual remained at least partially located within the virtual fall zone for at least the pre-determined amount of time.

9. The computerized method for detecting of claim 1, wherein defining the virtual fall zone comprises the steps of:

receiving a selection of a fall zone from a choice of icons appearing on a screen of a display where a live video feed from the one or more 3D motion and sound sensors is visible on the screen;

receiving an indication to create an end point where the fall zone begins from a selection on the screen by an electronic cursor;

receiving a selection of a corner point for the fall zone from the electronic cursor selecting the corner point on the screen;

receiving selections for remaining corner points for the fall zone and receiving an indication to complete the virtual fall zone from selections on the screen by the electronic cursor.

10. The computerized method for detecting of claim 9, wherein a depth range box is displayed on the screen.

11. The computerized method for detecting of claim 10, wherein the depth range box is displayed on the screen within a portion of the completed virtual fall zone.

12. The computerized method for detecting of claim 1 further comprising configuring a type of alert to generate in the event that it is determined that the individual is at least partially located within the virtual fall zone for at least the pre-determined amount of time.

13. The computerized method for detecting of claim 1, wherein the computerized monitoring system determines if the individual has fallen by determining that a location of one or more specific body segments of the individual is within the virtual fall zone.

14. A computerized system for detecting when an individual has fallen within a fall zone and requires assistance, the computerized system comprising:

one or more 3D motion and sound sensors configured to capture live video data from an area in which an individual to be monitored is located;

a computerized monitoring system configured to;

define a virtual fall zone within the area that the individual is located;

receive video data from the one or more 3D motion and sound sensors wherein the video data from the one or more 3D motion and sound sensors comprises data representing 3D coordinates of body joints for the individual and a general skeletal outline of the individual;

using the data from the one or more 3D motion and sound sensors, determine that the individual has become at least partially located within the virtual fall zone;

determine that the individual has remained at least partially located within the virtual fall zone for at least a pre-determined amount of time; and

upon determining that the individual has remained at least partially located within the virtual fall zone for at least the pre-determined amount of time, automatically transmit an alert to at least one of a computerized communication system and a centralized monitoring system.

15. The computerized system of claim 14 further comprising a centralized monitoring primary display that is remotely located from the area, wherein a live video feed of the area received from the one or more 3D motion and sound sensors is continuously displayed on the centralized monitoring primary display.

16. The computerized system of claim 15 further comprising a centralized monitoring alert display that is a separate display from the centralized monitoring primary display, wherein the live video feed is displayed on the centralized monitoring alert display after the alert has been transmitted to the centralized monitoring system.

17. The computerized system of claim 14 further comprising a database in communication with the computerized monitoring system, wherein the computerized monitoring system is further configured to update the database regarding the determination that the individual remained at least partially located within the virtual fall zone for at least the pre-determined amount of time.

18. A computerized method for detecting when a monitored individual has fallen within a fall zone, said method performed by a computerized monitoring system and comprising:

defining a virtual fall zone within an area that an individual to be monitored is located;

receiving video data from one or more 3D motion and sound sensors capturing live video data from the area;

determining that the individual has become at least partially located within the virtual fall zone based on 3D coordinates of one or more body joints of the individual;

determining that the individual has remained at least partially located within the virtual fall zone for at least a pre-determined amount of time; and

upon determining that the individual has remained at least partially located within the virtual fall zone for at least the pre-determined amount of time, automatically transmitting an alert to at least one of a computerized communication system and a centralized monitoring system.

19. The computerized method for detecting of claim 18 wherein the virtual fall zone is proximate to a portion of a floor within the area.
